Wiring in the engine room is done. Manifold sits good just connecting the last electricity in the glovebox Skickat från min SM-G935F via Tapatalk
The fuelsystem is almost completed. And the engine received a big fan Skickat från min SM-G935F via Tapatalk
Quick question, i know the newer lexus use a canbus gateway to talk to there multiplexor system, and ive currently got a mercedes diesel in my is200 running through an arduino nano & canbus shield to drive my tacho, but was going to use the newer gateway to get my coolant gauge to work etc. did you manage to datalog the PID for coolant or did you just do tps, revs and wheel speed. Also are you sticking with the 2.47 rear diff ratio or changing this to the soarer ratio?
The coolant in mine was direct drive from the dash. Same with rev, tach, speedo. Abs signal. The only parts that was multiplexed in the is220 was the small digital display in the gauge cluster. But it should be close to the yaris if it's indeed canbus Skickat från min SM-G935F via Tapatalk
I think the ratio of the is 220 is 3.7 or 3.9, soarer was 4.038. Think it will be fine. Maybe I finally have some use of 1st gear in the r154 Skickat från min SM-G935F via Tapatalk
Is220d is definitely 2.47 and the larger size diff. Is250 is 3.9 and small size. Isf is 2.9 new is300h is 2.7. Ive an ls430 large diff in mine 3.26 same as supra. Tacho, speedo and fuel gauge are direct feed on is220d clocks. everything else is multiplex or from the gateway via canbus.
That means I will have a higher toppspeed right. Im using r154 with is220 diff Yeah like you say with the feeds. I found the Ids for almost everything. But like indicators and light etc was all direct drive. The only thing I needed that wasn't was the power steering. R154 1- 3.251 2- 1.955 3- 1.310 4- 1.000 5- 0.753 RA63 1 - 4.17 2 - 2.19 3 - 1.49 4 - 1.19 5 - 1.00 6 - 0.84 diff soarer diff is220d 2.937 and 3.266 and SE/SEL is 2.474. I remember that the gearing of the is220d was very ackward and it feelt like it should have an stronger engine. but also that some of the gears was very nice. but as i see here it looks like it will have lower gearing than the diesel. or about the same but with alot more power hopefully. the r154 was never nice to drive in 1,2 gear for me in the soarer. It felt like they was a little off actually for my driving style. But im going to try it before i decide. Skickat från min SM-G935F via Tapatalk
All is220d are 2.47 only is220d sports are 2.93 Your gearing will be very long like 37% longer than a 3.9 Can you send me some of the pids or are they in the format of standard obd2 already
Thanks for giving me heads up. Didn't think about it at all before. Lets see how it works. else the is300 differential fits right? About the pids the codes i was sniffing was not standard obd 2. The canbus system uses an extended protocoll with a lower and higher id. I lost most of my id's when my harddrives gave in a few months ago. i still have the software i implemented though but it requires some work to communicate with the canbus shield for the arduino. Heres a project which have the prius(sorry not yaris) id's thats pretty close to the lexus is220. We share the same id's but not the same checksum system. Like for me when controlling the steering ecu i needed the signal from the abs sensor (theres one abs and one other). 00 B4 00 00 00 00 00 FF FF BA, 00 B4 is the id, and BA is the checksum. but in my lexus the first FF was always 00. noRepeatsEngineOnOff.add(new CanbusMessage("2000", "B4", new String[]{"00", "00", "00", "00", "00", "00", "00", "BC"})); this is my only left over... and this is the speed standstill on 00 B4, which gives checksum BC, with the algorithm from the pdf bellow its easy to understand how its calculated. theres also an list of id's in the pdf bellow, but as said before the lexus doesnt completely match, but it helps you find the ID's. http://illmatics.com/car_hacking.pdf
i have scanned for PID's using arduino before , i just dont have an is220d or is250 to hand to data log. is300/is250 small frame diffs. your subframe accepts large frame diffs only.
